Lightroom; changing default external editor?

[Lani]

Trying to work out where I can set CS4 as the default external editor from LR...can't seem to access it from preferences menus. I am using LR 2.4. It keeps coming up as CS3?
Any ideas. :confused013

You in Develop Mode ?

Edit/Preferences

You can set an additional external editor there

Cheers, Darren...I was there but I had an inactive version of CS3 which must've been overriding it...removed that and is now recognising CS4.
